(CNN) - New Jersey Gov. Chris Christie on Friday is expected to announce whether he'll sign a medical marijuana bill that could expand options for patients seeking the drug and make it easier for children to qualify for the program.

Current law allows New Jersey patients to get medical marijuana, but the bill, S2842, would eliminate a limit on the number of marijuana strains that the state's dispensaries can cultivate - ostensibly making it more likely that they would carry versions that certain patients seek.
